If antenna misalignment is not required as per «8» above, connect the test equipment as shown inFigure 19 – Antenna misalignment with E-RIT tool (with Enhanced RIT tool) while inserting theappropriate IGAU type value as recorded in «5» and «6» above. If antenna misalignment is required,proceed directly to «19».10. Ensure that the base station is transmitting a signal in the desired sector.11. Adjust the bolts identified in Figure 15 until the X-Pol RT mounting hardware is sufficiently snug tohold the unit on the mast, but is loose enough to allow easy rotation of the unit by hand.12. Switch the NT on.13. Roughly align the X-Pol RT based on the Radio Network plan.14. Using the Enhanced RIT tool, fine align the X-Pol RT antenna to maximum field strength and recordthe Enhanced RIT tool level and LED status.15. Determine the calculated maximum received signal level (RSL) using the signal level calculator. Incomparing the measured RSL to the calculated RSL, both values should be roughly the same.16. Tighten the pole elevation and azimuth bolts to 4.07 Nm (36 in-lb) torque, and the vertical angle boltsto 10.85 Nm (8 ft-lb) torque.17. Verify the level measurement using the Enhanced RIT tool to ensure that the X-Pol RT is still alignedto provide the maximum level. If this level has changed, repeat the maximum alignment procedure.18. Switch the NT off, disconnect the test equipment and reconnect the IF cable to the NT. Switch theNT on.19. If antenna misalignment is possibly required as per «8» above, connect the test equipment as shownin figure 16 (with spectrum analyzer) while inserting the appropriate IGAU type and value asrecorded in «5» and «6» above.20.

If this recorded level is already 15 dB below the calculated RSL, naturalmisalignment due to the elevation relationship between the BS and TS has occurred and no furthermisalignment is necessary. Proceed to «29».28. If the measured RSL is not 15 dB below the calculated RSL, misalign the X-Pol RT antenna upwardsin the vertical plane until the RSL is 15 dB below the calculated RSL and record the value.29. Tighten the pole elevation and azimuth bolts to 4.1 Nm (36 in-lb) torque, and the vertical angle boltsto 10.85 Nm (8 ft-lb) torque.30. Verify the level measurement using the spectrum analyzer to ensure that the X-Pol RT is still alignedto the desired level in «28». If this level has changed, repeat «27-29».31. Switch the NT off, disconnect the test equipment and reconnect the IF cable to the NT. Switch theNT on.32. In the case where the desired sector’s X-Pol RBS Tx/X-Pol RBS Rx pair is horizontally separated by∼ 10 meters worst case, in order for an equivalent amount of CPE antenna gain to be seen by boththe X-Pol RBS Tx and the X-Pol RBS Rx, the CPE should be aligned to the mid point between theX-Pol RBS Tx and X-Pol RBS Rx. This task can be performed visually within a few hundred meterswhere the worst case at 100 m would yield ∼ 16 dB of CPE misalignment to both the X-Pol RBS Txand X-Pol RBS Rx respectively. In this case, no elevation misalignment is necessary. As weapproach the AMTR (distance depends on rain region), visual alignment to the mid-point of the X-Pol RBS Tx and X-Pol RBS Rx becomes more difficult but is not as critical whereby if the CPE werealigned to the X-Pol RBS Tx instead of the mid-point, the X-Pol RBS Tx would only have ∼ 1 dBstronger relative antenna impact to the X-Pol RBS Rx, which is acceptable.33. Record this azimuthal mid-point RSL. If this recorded level is already 15 dB below the calculatedRSL, natural misalignment due to the mid-point TS antenna pattern roll-off and/or the elevationrelationship between the BS and TS has occurred and no further misalignment is necessary.Proceed to «35».34. If the measured RSL is not 15 dB below the calculated RSL, misalign the X-Pol RT antenna upwardsin the vertical plane until the RSL is 15 dB below the calculated RSL and record the value.35. Tighten the pole elevation and azimuth bolts to 4.1 Nm (36 in-lb) torque, and the vertical angle boltsto 10.85 Nm (8 ft-lb) torque.36. Verify the level measurement using the spectrum analyzer to ensure that the X-Pol RT is still alignedto the desired level in «34». If this level has changed, repeat «33-35».37. Switch the NT off, disconnect the test equipment and reconnect the IF cable to the NT. Switch theNT on.4.2 – Commissioning the NTNote: To carry out the following phases of the Terminal Station commissioning, the link Base Stationmust be operational and its antenna correctly orientated.Considerations– Before commissioning the NT unit, complete the X-Pol RT unit adjustment procedures.– No adjustment is required for commissioning the NT.– To check the voltage at the mains connector terminals, use a measuring instrument (voltmeter).1.
